Summary
This protein negatively controls the expression of the transcription units that encode the proteins and enzymes required for the transport (nupC, nupG, and tsx) and the utilization of nucleosides (deoCABD, udp, and cdd). [More information is available at EcoCyc: EG10200].

What's a GeneRIF?
  1. CytR exhibits features of an electric potential sensor modulating its dimensions and landscape in a unique distance-dependent manner while binding target DNA.
    Title: Tunable order-disorder continuum in protein-DNA interactions.
  2. Results indicate that while CytR forms a well-ordered structure in solution, it is highly dynamic.
